thats what i figured, now, to sell the magnum build the he400 to obtain an he500? Let me ask this, and maybe i should move to the he500 forum, but my main thing is i want more lush mids, specifically upper mids, which the 400 does not have, and i cannot for the life of me get any eq to properly fix just that part. so, does the he500 have what im looking for? I loved the upper mids of the hd 598, but the rest of the spectrum was lacking. I dont care a ton for bass, i like the bass on the 400 dont get me wrong, but i could afford to lose some quantity for a more neutral hp while retaining that "planar magic".
